In Fort Myers Beach, August is identified by the highest average temperatures, reaching a peak of 88°F (31.1°C) and a low of 81.1°F (27.3°C).

Heat index

In August, the average heat index is computed to be a torrid 102.2°F (39°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. To cut down UV radiation exposure by about half, sport a wide-brim hat. Take note! The UV strength of the Sun elevates when reflected off water and sand.
